I just saw Treasure of the Sierra Madre, and all I can say is I love John Huston's movies. Beat the Devil, Key Largo, Man Who Would be King and African Queen are the ones i've seen, and they all are great adventure rides. Part of the fun of the story is being taken off to some far exotic land (The Florida Keys were more exotic back then) and seeing it in a way that you wouldn't have otherwise seen it.
Like Alfred Hitchkock, John Huston could be said to have been in a genre of his own (although nowhere near as prolific or as well-received by academics, of course).
I don't know if that genre of films still exists. We had Indiana Jones though or Romancing the Stone and that might have been the closest that we have had in the blockbuster era to John Huston. Maybe, the era is lost or maybe with the world having become more and more global
in the last 20 years, exotic places no longer exist. Still we can do that movie in a retro era.
